Efficacy and safety of hyaluronic acid fillers for lip augmentation in a Chinese population

Patient Satisfaction during Upper Lip Augmentation Procedures: V-Y in V-Y Technique Compared to Micro-fat Injection: A Randomized Clinical Trial

AIM

To compare two different techniques for lip augmentation: A surgical technique (V-Y in V-Y) and a filler technique (autogenous micro-fat injections), with a focus on comparing the patients' satisfaction using the Visual analog scale (VAS).

MATERIALS AND METHODS

This randomized controlled trial was conducted on 40 female patients, aged 18-45, who were outpatients at the Oral and Maxillofacial Surgery Department. The patients were randomly assigned with a 1:1 allocation ratio into two groups. The first group (n = 20) underwent the surgical procedure using the V-Y in the V-Y Technique. The second group (n = 20) received autogenous micro-fat injections using an abdomen fat extraction technique that was subsequently centrifuged. The VAS assessed the patient's satisfaction after 1 and 6 months.

RESULTS

There was a statistically significant difference in the evaluation of patient satisfaction with treatment 1-month post-procedure when comparing the surgical procedure group and the fat injection (p < 0.001), favoring the fat injection group. Moreover, there was a statistically significant difference in the evaluation of patient satisfaction with treatment 6 months post-procedure when comparing both groups (p < 0.001), favoring the surgical group.

CONCLUSION

The micro-fat injection technique had higher VAS scores reported by patients in the first month of treatment. In contrast, the surgical technique using the V-Y method was more favorably received by patients in the sixth month of treatment.

CLINICAL SIGNIFICANCE

The V-Y in V-Y technique may yield more favorable long-term outcomes for upper lip augmentation, while micro-fat injection is initially well-received by patients, but satisfaction tends to diminish over time.

Ellansé: Advanced Technology and Advantageous Selection of New Collagen Stimulating Agents for Face Rejuvenation

Facial injections have a comparative mature market and system in China, but all kinds of injection materials have their own advantages and disadvantages, even hyaluronic acid, as the most common injection material, can form an unnatural stiffness after injection. Currently, Ellansé, a biodegradable collagen stimulator, has shown superior aesthetic results while ensuring safety and naturalness, making it a more preferable choice for a variety of facial injections. The purpose of this review is to introduce the features and benefits of Ellansé, so that doctors in the field can better understand and learn how to use it properly and minimize the risk of complications, and have a better choice for the medical aesthetic field in China in numerous aspects. The papers with the keyword "Ellansé" is very few in number, and there is a lack of systematic overview. Ellansé itself has unique advantages for the Chinese population, as it is an attractive option for the treatment of aging face due to high patient satisfaction, long-lasting results and low side effects (Guo et al. in J Cosmet Dermatol 21(5):1959-1966, 2022). More clinical data will be available in the future to confirm its performance and longevity in various sites.
